Description
Beschichtetes Geschirr zum Coated dishes for
Zubereiten von Speisen Die Erfindung betrifft beschichtetes Geschirr, insbesondere Töpfe und Pfannen zum Zubereiten von Speisen. Preparation of meals The invention relates to coated dishes, in particular pots and pans for preparing meals.
Beim Zubereiten von Speisen, wie Braten, Drillen, Backen oder Kochen,stellt das Anhaften ("Anbrennen") der Speisen an den mit ihnen in Berührung kommenden Oberflächen des verwendeten Geschirrs, wie Pfannen, Bräter, Kasserollen oder Töpfen, ein Hauptproblem dar, da die nachfolgende Geschirreinigung dadurch erschwert wird. Besonders bei der fettarmen Zubereitung von Nahrungsmitteln tritt das "Anbrennen" leicht auf.When preparing food, such as roasting, drilling, baking or cooking the sticking ("burning") of the food to the surfaces that come into contact with them of the dishes used, such as pans, roasting pans, saucepans or pots, a major problem because the subsequent cleaning of the dishes is made more difficult. Especially at in the low-fat preparation of foods, "scorching" occurs easily.
Eine Innenbeschichtung des Geschirrs mit speziellen Materialien verhindert bzw. vermindert das Anhaften der Speisen bei deren Zubereitung. Am bekanntesten und am weitesten verbreitet ist die Beschichtung mit Polytetrafluoräthylen. Dieser Spezialkunststoff verhindert das Anbrennen und Ankleben der Speisen, das so beschichtete Geschirr ist daher leicht zu reinigen. Ausserdem kann ohne oder mit wenig Fett gebraten werden. Diese Anti-Haft-Beschichtungen sind zwar ziemlich kratzfest, doch ist die Abriebbeständigkeit der Kunststoffschicht in vielen Fällen nicht ausreichend. Spitze Gegenstände und scharfe Messer können Kratzer verursachen, die die Anti-Haft-Eigenschaften beeinträchtigen, trotz aller Versuche, die Abbriebbeständigkeit der Kunststoffschicht durch spezielle Zusätze zu verbessern. Ausserdem wird die Beschichtung durch ungewollte Überhitzung beschädigt und im Extremfall zerstört. Auch gesundheitsgefährdende Aspekte der Beschichtungsbestandteile werden heute diskutiert.An inner coating of the dishes with special materials prevents or reduces the sticking of the food during its preparation. Best known and the coating with polytetrafluoroethylene is the most widespread. This Special plastic prevents the food from burning and sticking, which is coated in this way Dishes are therefore easy to clean. It can also be fried with little or no fat will. These non-stick coatings are quite scratch-resistant, but that is In many cases, the abrasion resistance of the plastic layer is insufficient. top Objects and sharp knives can scratch the non-stick properties affect, in spite of everything Try the abrasion resistance to improve the plastic layer with special additives. In addition, the Coating damaged by unintentional overheating and, in extreme cases, destroyed. Health-endangering aspects of the coating components are also discussed today.
Es war daher die Aufgabe der vorliegenden Erfindung, beschichtetes Geschirr, insbesondere Töpfe und Pfannen, zum Zubereiten von Speisen zu finden, bei dem die Beschichtung unempfindlich gegen Abrieb und Überhitzung ist, keine Gesundheitsgefährdung auftreten kann und trotzdem das Anhaften der Speisen während des Garprozesses zuverlässig verhindert wird.It was therefore the object of the present invention to provide coated Find dishes, especially pots and pans, for preparing food, in which the coating is insensitive to abrasion and overheating, no health risk can occur and still the sticking of the food reliably during the cooking process is prevented.
Diese Aufgabe wurde erfindungsgemäss dadurch gelöst, dass die mit den Speisen in Berührung kommende Geschirroberfläche mit einer dünnen Schicht aus Aluminiumoxid, Chromkarbid, Titankarbid und/oder Titannitrid bedeckt ist.This object was achieved according to the invention in that the with the surface of the dishes that come into contact with the food with a thin layer Aluminum oxide, chromium carbide, titanium carbide and / or titanium nitride is covered.
Besonders bewährt haben sich hierbei Titannitrid und Titankarbid, wobei die Schichtdicke der Antihaftbeschichtung vorteilhafterweise û,5 bis 20 /um beträgt.Titanium nitride and titanium carbide have proven particularly useful here, where the layer thickness of the non-stick coating is advantageously from 5 to 20 μm amounts to.
Als Unterlagematerialien können alle bekannten metallische und nichtmetallische Geschirrwerkstoffe dienen, wie Stahl, Aluminium, Kupfer und deren Legierungen oder Glas bzw. Glas-Keramik. Die Beschichtung kann auf bekannte Weise erfolgen, beispielsweise mittels CVD-oder PUD-Verfahren. Durch nachträgliches Polieren lassen sich die Antihafteigenschaften der so abgeschiedenen Schichten noch verbessern.All known metallic and non-metallic Crockery materials are used, such as steel, aluminum, copper and their alloys or Glass or glass-ceramic. The coating can be done in a known manner, for example by means of CVD or PUD processes. The non-stick properties can be reduced by subsequent polishing of the layers deposited in this way.
Die erfindungsgemässen Antihaftschichten sind extrem abriebfest, temperaturbeständig und korrosionsfest. Sie zeigen eine hohe thermische Leitfähigkeit und ein sehr dekoratives Aussehen. Die Schichten sind sehr haftfest, sie können kaum abplatzen, eine Gesundheitsgefährdung ist ausgeschlossen. Sie verhindern das Anhaften Von Speisen selbst bei fettfreiem Garen vollständig.The non-stick layers according to the invention are extremely abrasion-resistant and temperature-resistant and corrosion resistant. They show a high thermal conductivity and a very decorative one Appearance. The layers are very adhesive, they can hardly flake off, a health hazard is excluded. They prevent food from sticking, even if it is fat-free Cook completely.
Als vorteilhaft hat es sich erwiesen, auf die Geschirrunterlagen erst eine dünne Titankarbidschicht und anschliessend eine dünne Titannitridschicht aufzubringen, beide zum Beispiel mit einer Schichtdicke von 5 /um.It has proven to be advantageous to first place on the crockery pads apply a thin titanium carbide layer and then a thin titanium nitride layer, both, for example, with a layer thickness of 5 μm.
Die Abbildungen I und II zeigen schematisch beschichtetes Geschirr. Die Innenseite (1) einer Pfanne istmit einer dünnen Schicht (2) aus Titannitrid bedeckt. Gemäss Abbildung II kann auf der Unterlage (3) auch zuerst eine Schicht (4) aus Titankarbid und anschliessend eine Schicht aus Titannitrid abgeschieden sein.Figures I and II show schematically coated dishes. The inside (1) of a pan is covered with a thin layer (2) of titanium nitride covered. According to Figure II, a layer can also be applied first on the base (3) (4) made of titanium carbide and then deposited a layer of titanium nitride be.
